Identification of Polycyclic Aromatic Hydrocarbons (PAHs) in the black crusts of Sicilian stone monuments: distribution and sources

Polycyclic Aromatic Hydrocarbons are a family of compounds with known carcinogenic potential; their properties of lipophilicity, low water solubility and adsorption to particles and sediments make them a potentially dangerous group of chemicals and a threat to the environment and its bio-resources. The concentrations of total Polycyclic Aromatic Hydrocarbons (PAHs) and 19 individual compounds in 8 black crusts sampled from historical building of Palermo (Italy) were analyzed, by gas chromatography/mass spectrometry (GC/MS) in selected ion monitoring (SIM) mode. PAH concentrations ranged from 78 to 9798 g/Kg of dry matrix. The resulting distributions and molecular ratios of specific compo…
